Numerical control device having function of simultaneously executing plurality of commands using data in table format

Abstract

In a numerical control device, a command read out unit sequentially reads out time or a position of an axis or a spindle which is a reference and a position of a different axis or spindle from the axis or the spindle which is the reference or an auxiliary function that are stored in a storage unit. A selection unit selects a processing unit that processes a command which is read out by the command read out unit on the basis of a definition set by a definition unit. The definition unit defines commands executed by each processing unit.

Description

RELATED APPLICATION DATA[0001]This application claims priority under 35 U.S.C. §119 and / or §365 to Japanese Application No. 2013-240038 filed Nov. 20, 2013, the entire contents is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a numerical control device controlling a machine tool and specifically relates to a numerical control device having a function of simultaneously executing a plurality of commands using data in table format.[0004]2. Description of the Related Art[0005]Japanese Patent Laid-Open No. 59-177604 and Japanese Patent Laid-Open No. 2003-303005 disclose a numerical control device having a path table operation function for which data in table format (path table) in which positions of axes or auxiliary functions are set with time, a position of an axis or a position of a spindle assumed as a reference is stored in a memory or a storage device connected thereto via a network, for driving the...

AI Technical Summary

Benefits of technology

The present invention provides a method for optimizing command execution by separately reading and executing commands, and obtaining execution results independently. This eliminates the need for a smooth movement path and optimized acceleration and deceleration during the execution process. Using a data format in table format, it is easier to create and reference the data for the next command. This reduces the cycle time and the need for additional information in the data format.

Problems solved by technology

Due to this, to create the data in table format is made complex.

This causes the cycle time to be longer.

The above-mentioned problem is not limited to changing the control mode but the above-mentioned problem occurs to the execution of a command which requires operation time using the data in table format for controlling the axes, the spindle or the auxiliary functions.
